Application led October 5, 19.22; Serial No. 592,653.

Toy all whom it may concern:

Be it known that LABS ENGnsn'r, a citizen oi" the United States,residing at Seattle, in the county of King and State of Washington, hasinvented certain new and useful Improvements in Roof-Plate Forms, 'ofwhich the following is a specification.

The invention relates to roof plates for forming roofs.

The object of the invention is to provide a construction which willpermit of readily and quickly assembling a series of interitting platesto form water and iireproof roof structure.

The invention also comprehends improvements in the details ofconstruction and arrangement of parts which will be hereinafterdescribed and particularly pointed out in the claims.

In the drawing:

Figure l isa plan view of the shingles in roof forming relation.

Figure 2 is a sectional view on line 2-2 of Fig. l.

Figure 3 is a shingles.

Figure 4 is a sectional view illustrating the modified form of means forsecuring one shingle to another.

The plates are constructed exactly alike, and a description of one will,it is thought, be sufficient.

1 indicates the plate as a whole, same being somewhat longitudinallytapered to form a thin and a thick end indicated respectively at 2 and3. The thick end 3 is provided on its underside with a cut away portionshown at 4, which also forms an abutting flange 5. In the under surfaceof the plate is one or more recesses 6, which open into the cut awayportion 4. Embedded in the thin end 2, are thin metallic strips 7, theprojecting portions thereof being provided with perforations 8.

On one side edge of the plate is a metal vertical flange 9, having itsend embedded in the material of the plate, while on the opposite edgethere is a metal flange 10 having one end embedded in the material ofthe plate, and its opposite end turned up and then down as shown at 1l.The flanges 9 and l0 terminate short of the edge of the thin end of theplate, as shown at 12, to permit assembling of the plates when forming aroof. The plates are formed of ceperspective of one of the ment or likematerial, except of course the strips 7 and the iianges 9 and l0.

In use, a plate is laid down and fastening means l5 are passed throughthe openings 8 in the strips to hold the individual plates in position.Then another plate is put down in alignment with the preceding platewith the cut away portion 4, lying over the thin end 2, of the rstplate, the flanges 9 and l0 terminating short of the thin edge at l2,permitting of this interfitting relationship. The joints between theabutting flanges 9 and the abutting lianges 10 are soldered as indicatedat 20, to form a seal. By this means, a row of plates can be assembledand secured with their respective ends overlapped to form a water tightJoint.

Plates placed along one side of those assembled receive the verticalflanges 9 and plates on the other side have their vertical flanges 9covered and protected by the downturned flanges 10, as will be obvious.

In lieu of the fastening means passing through the strips 7, I mayprovide each plate with an opening 20 directly above the recess 6, andprovide a thin plate 2l, on the upper edge of the plate to Jform apocket, and then roughen the strip 7. When using this means of securingthe plates, the strips 7 are inserted in the pocket formed by therecess, and then cement is poured through the opening 20 with the resultthat when it sets, a binding lock is formed with the roughened surfacesof the strip.

What I claim is:

l. A roof plate comprising a thick end having a cutaway portion at oneend with a recess adjacent thereto and communicating with the cutawayportion, and a thin end having a thin projecting strip in alignment withthe recess, one side edge of the plate having a vertical flange, and theopposite side edge of said plate having a turned ange.

2. A roof composed of a series of plates, each plate having a transversecutaway portion with a recess communicating therewith, a thin stripextending from the opposite end of the plate, a vertical flange on oneside edge of the plate, and a vertical turned down flange on theopposite side edge, whereby when the plates are assembled in roofformation, the ends of adjacent plates lying in superimposed relationwill t under and inv the cutaway portion of adjacent plates and the thinstrip will lit into the recesses, and the anges of adjacent side rVplates in the same horizontal row will interlo a metal strip embeddedin one edge of the plate and bent upwardly to form a Vertical flange, a`metal strip on the; opposite edge of the plate bent upwardly and then.down to form an overhanging flange, said flanges terminating short ofone end of the plate, and metal strips extending from the upper edge ofthe plate between the flanges.

In testimony whereof I affix my signature.

LABS ENGESET.
